Thanks, for this tutorial! Very helpful.
I'm having a hard time getting a track and am wondering if it's a software issue or if I'm doing something wrong. I've attached a screen grab. I can get a solid result with only one tracker, but not more than one.

I've used this workflow for most of my projects.
You take an EDL or XML into RedCineX, set your export to R3D Trim, set your handle lengths, and the export. It creates trimmed R3D files that you can easily manage and import into your grading app of choice.

Once the Printer Lights hotkey's are turned "ON" you can use hotkeys to make full, half, and quarter adjustments. I recently added a Stream Deck to my setup and programmed the printer lights to it, which makes the process much faster.
